I agree, it isn't clear from the documentation. I've looked in the  
BibTeX documentation, The LaTeX Companion (2nd Edition), Guide to  
LaTeX (4th Edition), LaTeX - A Document Preparation System and More  
Math Into LaTeX (4ht Edition) and all were unclear about the spaces.  
Of course the proof is in the pudding and if bibtex chokes the answer  
is clear.

I'd guess leading spaces might be ignored so I'd leave them out!

Good Luck,
